| Abstract: | In this study, by using magnesium salt, the supernatant of ammonia nitrogen and phosphate reaction, we make the formation of magnesium ammonium phosphate precipitation, namely MAP. Using MgCl2 6H2O and Na2HPO4 12H2O as the precipitant, the author research the factors that influence the effect of denitrification. The author get the optimum process conditions, the reaction time 180min, pH10, Mg：P：N 1：1：1, temperature35℃, ammonia nitrogen removal rate of 84.23%. |
